In this paper we want to, on the one hand, translate the Common Declaration of the Holy Father Francis and Ecumenical Patriarch Bartholomew I, signed 30 November 2014, and, on the other, to provide a brief theological interpretation. In the first chapter we have translated document in the Croatian language. In the second chapter we have interpreted every part of this Common Declaration and we attempted to show where the similarity with their previous Common Declaration and where different accents. In the conclusion of the paper we have tried to see what is the importance of this new Common Declaration. Pope and Patriarch require that the Church of the East and West together performances in the fight against wars in the World, the persecution of Christians and all other people and call the responsible institutions and all people to do what belongs to them.
